Abstract

PURPOSE:To enable a reciprocating motion to be performed and obtain an efficient mechanical driving force, by dividing a piezoelectric element section set on an oscillator, in the longitudinal direction, and by applying high frequency voltage to the one side divided piezoelectric element section. CONSTITUTION:So far as a piezoelectric element section 2 is concerned, an electrode on the one-side surface of a piezoelectric element is divided into two to form divided electrodes 61, 62, and an electrode 60 on the other side surface is formed as a common electrode. When high frequency voltage is applied to either one of the divided piezoelectric element sections 21, 22 of an oscillator to excite the sections, then they are oscillated up and down in the longitudinal direction of the oscillator 1, and in the vertical direction, a maximum amplitude point is moved on the slant because the divided piezoelectric element sections 21, 22 are arranged to be inclined in the width direction. Accordingly, when the voltage is applied alternately to the divided piezoelectric element sections 21, 22, then a reciprocating swing motion is performed. Accordingly, a contact member 4 in contact with the maximum amplitude point of the oscillator 1 is linearly moved. In this manner, the oscillator 1 can be supported by a base end section, the nodal point of oscillation, and the like, and so oscillatory attenuation is reduced, and efficiency is improved.
